Deepstream gstreamer plugin blacklist in custom docker container

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi all,

I need some help with debugging Gstreamer blacklisting Deepstream plugins in my docker container. I’m not running on JetPack, but rather on an OS called Balena OS. I believe the issue is not related to the OS, but rather the installation.

The OS is built on L4T 32.6.1, and I’m using a barebone TX2NX base image provided by Balena. The top layers of the image are shown below. We are using cuda 10.2, tensorrt 8.0.1 and deepstream 6.0.0.

# base image common to both build and run images

... rest of our application

The installation seems straightforward, and is very similar to the installation on Jetpack 4.6, apart from the BSP download and applying debs manually.

For some reason, gstreamer is blacklisting some of the deepstream plugins. I’ve manually check if the dependencies for the shared library exist by using ldd, and they all shows up fine. I also checked the output of ldconfig -p to ensure the gstreamer plugins exist, and they do. I’ve attach the output when doing GST_DEBUG=4 gst-inspect-1.0 -b after removing the cache file in /root/.cache/gstreamer-1.0.
inspect-output.txt (151.5 KB)

There’s a few stderr out regarding nvbuf_utils: Could not get EGL display connection, but the DISPLAY env var is already unset, and this device does not have any display output as well.

Any help pointing towards where to look into fixing this issue would be appreciated. Thanks!

Can you install “libssl1.0.0” instead of “libssl1.1”?

Can you find “/usr/lib/aarch64-linux-gnu/tegra/libnvbufsurftransform.so” in your docker?

What is the result of “ldd /usr/lib/aarch64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_tracker.so”?

Some updates,

I also try to use gdb to see whats’ causing the segfault as well, it seems like it’s missing something called pthread_mutex_lock.c?

nvbufsurftransform: Could not get EGL display connection

not sure if this helps too.

Seems the versions are not compatible.

Have you tried to install these packages directly in host and run?

7

No I have not, I’ll try and do that.

Any idea which package is running the wrong version?

Here’s the output of valgrind from running valgrind gst-inspect-1.0 /usr/lib/aarch64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_tracker.so

Segfaults and coredumps seems to be coming from libEGL_mesa. Still investigating more

Either the driver is wrong or your “DISPLAY:0” is not Nvidia driver based.

Update:

I was able to solve the issue, the issue was not a missing library, but rather tegra-egl path is not in the ldconfig configs.

I updated the BSP installation part of the docker container to include echo "/usr/lib/aarch64-linux-gnu/tegra-egl" > /etc/ld.so.conf.d/nvidia-tegra-egl.conf and that fixes the issue of gstreamer blacklisting the deepstream plugins.

However, whenever I do a gst-inspect-1.0 nvtracker to show its information, it would still crashes from a seg fault (similar to what I posted in my earlier post). This however doesn’t seem to cause any issue when running the sample apps.
